Nope
With the only person I know IRL called Beth, it's short for Beatrice

I thought Beth was short for Elizabeth.

It can be short for either, I believe

Bert would be more appropriate for Beatrice.

It'd be more appropriate for her too.

In my case, it is.
I've never heard it as a version of Beatrice. These days it's more likely to be short for Bethany.

Then again, I never understood how Daisy was short for Margaret, Sally was short for Sarah, and Dick was short for Richard.

There is no way Daisy is short for Margaret
or Sally for Sarah, that's just stupid

No, they are, traditionally.
The Daisy thing comes from the fact that there is a flower called a marguerite which is a big daisy type flower.

that's not short for. That'd be like calling me Cat.
